Cambodia B2G E-Invoicing for Government Suppliers

Short answer

Government suppliers are a concrete audience in Cambodia’s e-invoicing rollout. GDDE held training for suppliers of 14 ministries in 2026, which makes B2G invoice workflows a sensible place to start readiness work. It does not establish that every Cambodian business is already under the same mandate.

What to remember

• GDDE has publicly trained suppliers serving 14 ministries.
• Scope should be checked by entity and procurement workflow.
• ERP teams should map document creation, status and correction ownership.

Why B2G is the first discovery question

A supplier may need to align invoice preparation with ministry purchasing, buyer data and acceptance steps. The exact requirement depends on the official rollout phase and the supplier’s own contract context.

Build a supplier-ready workflow

Identify invoice source systems, government buyer identifiers, purchase order references, adjustment documents and who reviews a rejected invoice. Keep the evidence linked to the original ERP transaction.

Questions to take into discovery

1. Which ministry or public body is the buyer?
2. What official phase applies to this supplier?
3. How will a rejection reach the ERP user who can correct it?

Quick questions

Is Cambodia e-invoicing mandatory for all businesses?

The cited GDDE training supports a government supplier use case, not a blanket claim that all businesses have the same obligation.
